In my last post I mentioned this terrific picture book on architecture.
It is an ABC book of architectural terms -- great for a lot of elementary grade levels. I have used it with grades 1 through 5. Last week 5th graders took the term "capital" (as in the carved top of a column) and launched a whole discussion of Greek columns. One boy knew a LOT about keystones (top of an arch) and described how an arch can collapse -- amazing what they know!!
If you do any architectural art, this is a resource you might want to have!
